I keep getting the following error message when trying to use the 3D component of CS6:

"Could not complete your request because 3D functionality is currently disabled due to OpenGL being disabled."

Well, that's not the case. I have Use Graphics Processor checked and Advanced selected for Drawing Mode. The other OpenGL features and enhancements are working fine. I cannot however import, create or manipulate 3D objests without getting the above error message. Any ideas?

You are instructing Ps to load 2 separate and non-compatible 3D engines when you do this. Never point additional plug-in paths to older Ps versions; it only causes problems. If you have 3rd party plug-ins that you wish to load in mulitple versions of Ps, then either reinstall them for each Ps version, or install them to a distinct custom directory away from the Ps installed plug-ins.
